Abstract
Provided are a laminate including a substrate; and a laminated structure including two or more kinds of layers having different specific acoustic impedances which is disposed on the substrate, in which the number of the layers constituting the laminated structure is 10 or more, a thickness of a layer having the largest thickness among the layers constituting the laminated structure is 8 nm or less, and in the laminated structure, a CV value defined by a standard deviation of a layer thickness/average layer thickness is 0.05 or more, and a building material, a window material, and a radiation cooling device including the laminate.
